Mobile Device Control System via Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current unmanned vehicle control systems are limited by allowing only one-to-one control of a single vehicle, requiring controllers to be in the same local network and necessitating network address resets when users change locations.
Innovation Solution
A mobile device controlling system comprising a mobile device, a controlling terminal, and a server that enables multiple mobile devices and terminals to connect, with modules for establishing connections, transmitting information, and controlling operations, allowing secure access and preventing multi-terminal control through authentication and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a one-to-one control system is used for unmanned vehicles, then the control connection is simple and stable, but the system cannot support multiple devices controlling multiple vehicles and requires network address resets when users change locations
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between controlling terminals and mobile devices. The server manages connection relationships, stores binding information between devices and vehicles, and facilitates control operations without requiring direct peer-to-peer network connections. This resolves the contradiction by enabling multi-device control through the intermediary server while keeping individual device complexity low.
2Adaptability or versatility
If controllers must be in the same local network as vehicles, then the control connection is direct and reliable, but users cannot control vehicles when changing locations
Solution Approach 1:
The server acts as a network intermediary that enables control connections independent of local network boundaries. When a user changes location, the controlling terminal communicates with the server over the internet, and the server retrieves the bound mobile device information to establish control. This maintains connection reliability through server-mediated communication while enabling remote control across different locations.
Solution Approach 2:
The system performs preliminary binding between mobile devices and unmanned vehicles before actual control operations. The server stores these pre-established relationships, so when users change locations, the control connection can be quickly re-established using the pre-bound device information without requiring network address resets or re-pairing procedures.
3Adaptability or versatility
If multiple terminals can control multiple vehicles, then the system versatility is improved, but security risks increase and exclusive control cannot be ensured
Solution Approach 1:
The patent implements authentication feedback mechanisms where the server verifies controlling terminals before allowing control operations. The system checks whether the terminal is authorized to control the target vehicle based on pre-bound mobile device information. This feedback loop ensures that only authenticated terminals can establish control, enabling multi-terminal versatility while preventing unauthorized access and ensuring exclusive control rights.
Data Source
AI summary
A mobile device controlling system includes one mobile device of a plurality, a controlling terminal of a plurality, and a server. A method for the system is also described. The one mobile device of the plurality includes a connection establishment module, an information transmission module, and an operation module. The connection establishment module transmits on startup a connection request to a server to establish a connection and the information transmission module transmits mobile device ID and status to the server. The operation module receives feedback from the server as to one verified controlling terminal within the plurality and the mobile device can be exclusively controlled by that terminal according to the feedback.
